Shopify Fulfillment Network help and support
Shopify Fulfillment Network (SFN) fulfillment centers operate Monday to Friday, from 8:00 am to 5:00 pm in their local time. Some holidays impact fulfillment center hours of operation.
If you aren't able to find the information you need on the help center, then you can contact the SFN support team. The way to contact the SFN support team depends on whether you're a merchant or an SFN Partner.
